A human rights organization and lawyers for a Saudi man accused in the 2000 bombing of the USS Cole demanded Tuesday that Polish prosecutors investigate the terror suspect's detention and treatment at a CIA prison once housed in Poland.

Prosecutors will seek the death penalty for self-proclaimed Sept. 11 mastermind Khalid Sheikh Mohammed and four other Guantanamo Bay detainees, who will be sent to New York to face trial in a civilian federal court, Attorney General Eric Holder said Friday.

Amid revelations that U.S. interrogators threatened terror suspects with handguns and an electric drill, Attorney General Eric Holder opened a preliminary review Monday to determine whether criminal prosecutions are warranted in some detainee abuse cases.

The CIA's internal investigator found that agency interrogators conducted mock executions of terror suspects and in one case threatened a detainee suspected in the USS Cole bombing with a gun and power drill, congressional officials said late Friday.

President Barack Obama planned to meet Friday with families of 9/11 victims and the 17 sailors killed in the bombing of the USS Cole, responding to anger over delays in bringing terror suspects to trial.

President Obama was spending time with families of 9/11 victims and the 17 sailors killed in the bombing of the USS Cole after a senior Pentagon judge dropped charges against an al-Qaeda suspect in the Cole attack being held at Guantanamo Bay.
